Yes because you don't have an AE or AF version radio and do not have the problems it fixes
Just got it done. It takes 2 hours (I watched the progress bar the entire time, it really does) and they do it via your obd. You have to take the car in.
That said, it is totally worth it. Sound quality is better, mono sound is fixed, and track titles show. It also feels snappier.
My car was tuned and switched back to stock. Didn't say a word or affect anything. Switched it back after and all was good.
Out of curiosity, what tune do you have? (GIAC, APR, REVO)

On RCD-510 hold down setup for a number of seconds you get to a menu where you can see it
